Need some help,

I used to be up to date on this stuff ten years ago lol, I think someone is possibly scamming me or trying to, I still have an open line of communication with them. I wondered if someone could help me check them out a bit and do some investigative work on the site and see if there actually scamming or if its lagitimate. the site they sent me is ten years old in poland. But the site im actually “working” in is much newer 34 days or so, not sure if there even together or if im being played. any help would be amazing
